"project could not save [download]" message on desktop

I'm on the desktop version, I guess this is default on scratch when your project is too large for the server, but when I'm on desktop it's a weird message. When I click download and then cancel, it does say it saved the project in the top-right corner.

Btw when I click the X it doesn't save at all.
